Amber & dark lager
Czech amber lager
A Bohemian amber lager balancing caramel malt against Saaz hop character, sitting between the pale and dark Czech beers.
- Strength
- 4.4–5.8% ABV
- Bitterness
- 20–35 IBU
- Colour
- Amber to copper
- Serve at
- 6–9°C
Also known as polotmavé, polotmave, Czech half-dark lager.
Czech amber lager takes the soft water, Saaz hops and decoction character of Czech brewing and adds caramel and Munich malt. The result keeps the drinkability of a pale Czech lager while adding a bread-crust and light toffee depth, and the hop bitterness holds its own against the extra malt rather than being buried.
Sold as polotmavé, meaning half-dark, and usually found alongside the pale and dark versions in the same brewery's range. It is the least exported of the three and one of the most rewarding to find.
Look for the same softness that defines the pale Czech beers — this is a caramel-forward lager that should still finish clean and quenching rather than sticky. Where it goes wrong is sweetness: the extra malt makes it easy to leave too much residual sugar, and a polotmavé that clings has lost the drinkability that is the whole Czech idea.

How it tastes
BeerHQ’s own comparative scale, not a measurement. Each bar is a range because a style is a span of real beers rather than one beer.
Appearance and character
| Colour | Amber to copper |
|---|---|
| Clarity | clear |
| Head | Off-white, dense |
| Fermentation | Bottom-fermented (lager). Fermented cool with Saccharomyces pastorianus, which settles out, then conditioned cold. The cooler process suppresses yeast-derived fruitiness, leaving malt and hop character exposed. |
| Origin | Czechia — Bohemia |
| Tradition | Bohemian pale lager brewing |
Measurements
Conventional ranges published by style bodies, not a specification. IBU measures iso-alpha acids in a lab and does not track perceived bitterness — compare it against the sensory scale above rather than reading it as a flavour rating.
| Measurement | Typical range |
|---|---|
| ABV | 4.4–5.8% ABV |
| IBU | 20–35 IBU |
| Colour | Amber to copper — 10–16 SRM, 20–32 EBC. |
| Original gravity | 1.044–1.060 |
| Final gravity | 1.013–1.017 |
| Carbonation | 2–3 vol CO₂ |

Freshness and storage
Czech amber lager shows best within 3–6 months of packaging. After that it declines in quality rather than becoming unsafe.
No benefit from keeping. Sound for its window and then slowly less good. Nothing bad will happen quickly, but nothing good happens either.
- Sound well past its window, but nothing in it improves with keeping. Drink it while it is fresh.
What changes with time
- Staling. The general, gradual loss of freshness that affects all beer, accelerated sharply by warmth. Months, and roughly twice as fast for every 10 °C warmer.
In the package
- Aluminium can — No light can reach the beer, so lightstrike is impossible in this format.
- Brown glass bottle — No format-specific concerns beyond the general advice above.
- Keg — No light can reach the beer, so lightstrike is impossible in this format.
Old beer tastes worse; it does not become dangerous. Ethanol, low pH, hop compounds and the absence of oxygen make packaged beer hostile to the organisms that cause foodborne illness. The exception is a compromised package — visible mould at the closure, a pierced or rusted can, a lifted cap — which is a reason to discard the beer regardless of its age.
Guidance, not an expiry date. How a beer is stored matters more than the date printed on it, and staling roughly doubles in rate for every 10 °C. See storage and freshness for the full model.
What to eat with it
- Chorizo
Paprika and red fat need caramel malt to meet them and Saaz bitterness to clear them. A pale lager is lost here.
- Adobo
Beer and dish carry similar weight, so neither flattens the other.
- Gyoza
Beer and dish carry similar weight, so neither flattens the other.
- Ham
Beer and dish carry similar weight, so neither flattens the other.
- Pad Thai
Beer and dish carry similar weight, so neither flattens the other.

Faults to watch for
How it got here
Czech amber lager does not have a separate history of its own. It is a reading of Czech premium pale lager, and that is where the account belongs — repeating it here would be a second copy of one story.
How it is made
The steps that shape this style in particular, rather than the ones every beer goes through.
- Decoction mash — Raise a mash to its next temperature step by removing part of it, boiling that portion and returning it — the traditional continental method.
- Diacetyl rest — Raise a fermentation’s temperature near its end so the yeast reabsorbs and reduces the diacetyl it produced earlier.
- Lagering — Store beer cold for an extended period after fermentation to clarify it and produce the clean, rounded character lagers are named for.

Evidence
What BeerHQ knows about this, and how. Every statement carries the state of the evidence behind it rather than being presented flatly as fact.
On Decoction mash
Whether decoction mashing produces a malt character that a well-executed step mash with modern malt cannot is genuinely disputed within the trade.
— Many traditional brewers and a substantial body of brewing literature hold that boiling part of the mash develops melanoidin character that cannot be reproduced otherwise.
— Several breweries historically associated with decoction have moved to step mashing without their beers being widely reported as diminished, and blind comparisons have not established a consistent difference.
The practical justifications for decoction — hitting temperature steps without a thermometer, working with undermodified malt — have both disappeared. What remains contested is whether the flavour justification stands alone.
Genuinely contested Credible sources disagree, so both positions are given rather than one.

On Bohemian pale lager brewing
Bohemian pale lager combined exceptionally soft local water, Moravian pale malt and Saaz hops, a combination that suited a very pale beer in a way most European water of the period did not.

On Crystal malt
Crystal malt is produced by stewing wet germinated grain so that starch converts to sugar inside the husk, then kilning so that sugar caramelises in place — which is what distinguishes it from ordinary kilned malt.

On Crystal malt
Crystal malt contributes sugars that brewing yeast largely cannot ferment, which is why it adds residual sweetness and body rather than alcohol.

On Diacetyl
The buttery or butterscotch character described as diacetyl is 2,3-butanedione, a vicinal diketone formed outside the yeast cell by oxidative decarboxylation of alpha-acetolactate.

On Diacetyl
Diacetyl has one of the lowest flavour thresholds of any beer compound, detectable by many tasters at concentrations in the region of 0.1 mg/L or below, with substantial variation between individuals.
Backed by a source
Sources: Beer: Tap into the Art and Science of Brewing — print; Technology Brewing and Malting — print
On Diacetyl
A low level of diacetyl is traditional and accepted in some Czech pale lagers and in some Yorkshire and Scottish ales, where it contributes a rounded buttery softness the brewers are not attempting to remove.

Sources: Tasting Beer (2nd edition) — print; The Oxford Companion to Beer — print
On Diacetyl rest
Raising a fermentation to 16–20 °C near its end accelerates yeast reuptake and reduction of diacetyl, which is slow at lager fermentation temperatures and is interrupted entirely if the beer is crashed cold too early.
Backed by a source
Sources: Yeast: The Practical Guide to Beer Fermentation — print; Technology Brewing and Malting — print
On Diacetyl
Diacetyl reaches beer by two unrelated routes: as a normal fermentation by-product that healthy yeast subsequently reabsorbs, or from bacterial contamination — chiefly Pediococcus — which produces it continuously and cannot be rested out.

On Lagering
Carl von Linde’s mechanical refrigeration, first installed in a brewery in the early 1870s, freed lager production from dependence on natural ice and cold cellars.

On Oxidation
In strong dark beer the same oxidative chemistry produces sherry, port and dried-fruit character that many drinkers actively seek, which is why oxidation is a defect in a fresh pilsner and part of the appeal of an aged barley wine.

On Oxidation
The wet-cardboard character of stale beer is attributed principally to trans-2-nonenal, a carbonyl formed from lipid precursors and perceptible at extremely low concentrations.

trans-2-Nonenal, a product of lipid peroxidation, is the compound behind the cardboard or papery flavour characteristic of stale beer.

On Saaz
Saaz is a low-alpha variety with a high humulene fraction relative to myrcene, which is the compositional basis of the delicate herbal and floral character associated with Bohemian pale lager.
